Uniband#
The Uniband
benchmark measures the cumulative bandwidth and message
rate values. To achieve this, the first half of ranks communicates with
the second half using MPI_Isend/MPI_Recv/MPI_Wait
calls. In case of
the odd number of processes, one of them does not participate in the
message exchange. The bunch of MPI_Isend
calls are issued by each
rank in the first half of ranks to its counterpart from the second half
of ranks. The number of messages issued at each iteration step is
defined with the MAX_WIN_SIZE
constant. The same buffer is used for
every send event in the iteration.
